Japanese 日本語 Nihongo is an East Asian language spoken by about 128 million people, primarily in Japan, where it is the national language. It is a member of the Japonic (or Japanese-Ryukyuan) language family, and its relation to other languages, such as Korean, is debated. Japonic languages have been grouped with other language families such as Ainu, Austroasiatic, and the now-discredited Altaic, but none of these proposals has gained widespread acceptance.
